The information processing unit and the probes are kept in a case that protect from transformation damage. 5 The circuit diagram, principles of operation, indicators and controls 5.1 Block-diagram The device includes the electronic module and sensor, attached with the connector. Detachable connector is on the upper front surface of the case. Navigation buttons are on the front panel, as well as the graphic indicator. The battery located in the lower back spot of the case under the cover in the compartment for batteries. 5.2 Operation principles Operation of the device is based on measuring oscillator frequency with coil of eddy current parametric converter in the circuit. The frequency of the oscillation depends on covering thickness. The result of the measuring is indicated on the display. NOVOTEST TP-1 coating thickness gage 10

12 5.3 Device display Display indicates the measured thickness of coating in mm or µm. The charging level of batteries and the type of the connected sensor also shown on the display. 5.4 Device keyboard Keyboard: Keys function: turn on/off set zero the measuring scale options.

13 6 Device Usage 6.1 Preparation for use Work with batteries Connect the sensor to the connector on the panel of the information processing unit. 1. Install battery in the battery compartment using polarity. 2. For checking the charge of the battery press and hold the button. 3. The Level of the battery charging is shown on the left upper corner of the display as a small battery icon. The dark battery color means the battery is fully charged. During discharging the battery icon segments disappear consecutively, from left to the right. One dark segment or absence of segments means that the battery needs recharging. The battery icon is present on the display in any mode of the device operation. 4. For charging the battery turn off the device pressing the button After that take off the battery from the battery compartment and charge it according to p After installing the recharged battery in the battery compartment turn on the device.

14 6.1.2 Charging the battery For charging the batteries: install the battery to the charger; connect the charger to the mains power supply. The battery will be fully charged in approximately 14 hours. It is forbidden to leave the charger alone during charging. After long storage period the battery needs recharging once every 2 months, even if it was not used. 6.2 Turning on the device Prepare the device for use according to p.6.1 and turn on it pressing the button. Logo appears on the display after pressing the button: After that the device is ready for operation and on the display the following information will appear: NOVOTEST TP-1 coating thickness gage 13

15 F-2 type of sensor 0,000 thickness of the covering value The device is ready for measurements. 6.3 Measurements Prepare the device to work in accordance with p.6.1. and turn on the device in accordance with p Install the sensor perpendicularly on the surface and press it steadily Wait for constant value of thickness of the covering on the display Lift the sensor from the surface and raise it in air After lifting the sensor in the air the display will indicate the last result of the thickness of the covering, which will be changed just after the next measurement Indication of the name of the sensor becomes inverted. The following measurement will be possible after indication of the name of the sensor takes the usual style. NOVOTEST TP-1 coating thickness gage 14

16 Note: Zero setting is recommended for the sensor according to p in the case of changing conditions of use (considerable change of the temperature, conduction of the material) at first activation of the sensor. 6.4 Measurements of average values The automatic averaging mode provides a default calculation of final measurement result in the arithmetic mean value together with the last measurements For switching on the mode of averaging press and hold button, for more than 2 seconds On display the following information will appear: Measurement average Last measuremen t Counter of the measurements NOVOTEST TP-1 coating thickness gage 15

17 6.4.3 For resetting measurement average and beginning new series of measurements press button To return from mode with averaging press and hold button for more than 2 seconds. The device will return to the usual mode. 6.5 Scales of the measured value For choosing the scale of the measured value (mm or µm) press The chosen scale will be indicated on the display. 6.6 Calibration To provide an adequate measurement with the device of the real thickness of the covering calibrate the device. For it you need to prepare a sample of the tested part similar or close in geometric, electrophysical properties and in the type of mechanical treatment of the tested product. NOVOTEST TP-1 coating thickness gage 16

18 6.6.1 Setting zero Install the sensor perpendicularly on prepared sample without covering normal to the surface and press it steadily.wait for indications to remain constant Press button, after that figures: 0.000; 00.00; 000.0; or 0 will appear on the display depending on the type of the sensor and used scale For checking the accuracy of the setting zero make repeated measurements on the prepared sample without covering. Reading must be within the range of 0±2 µm. Note: Zero setting is recommended for the sensor according to p in the case of changing conditions of use (considerable change of the temperature, conduction of the material) at first activation of the sensor One-point correction Switch the mode of the measurements with averaging in accordance with p Prepare the sample for calibration, for it put the sample of the reference thickness tightly against the smooth base Make no less than 3 measurements. NOVOTEST TP-1 coating thickness gage 17

19 Switch the mode of correction. For it press twice button, after that two quick presses, and after that again press twice Indication of averaged value of the thickness of the covering will become inverted. Display will be as follows: Use buttons and for setting adequate average measurements to the rated value of the thickness of the covering Press button for ending onepoint correction The inverted indication of the value in the right part of the display means that the device use settings with one-point correction. NOVOTEST TP-1 coating thickness gage 18

20 After above procedures make several test measurements. If inaccuracy does not exceed value specified in p.2.4. the device is ready for use, otherwise repeat the calibration. Note: After changing a part for measurements for a part with significant difference in properties, calibrate the device for the new part again Resetting one-point correction In case of wrong calibration for resetting the sensor make measurement on a sample or a part without covering, and after that press and hold button for more than 5 seconds Indication of the scale in the right part of the display will cease to be inverted. 6.7 Turning off the device For turning off the device press and hold button If measurements were not made during 1 minute, the device would switch off automatically.
